[jira] [Commented] (KAFKA-17601) Inter-broker connections do not expose their clientSoftwareName and clientSoftwareVersion tags

["Chia-Ping Tsai (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-17601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17896849#comment-17896849 ] 

Chia-Ping Tsai commented on KAFKA-17601:
----------------------------------------

The root cause is that we set the clientInformation "after" the `RequestContext` is created. Hence, there is only empty clientInformation. 

https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/network/SocketServer.scala#L1145

we will file a patch to fix it later

> [KIP-511|[https://cwiki.apache.org/confluence/display/KAFKA/KIP-511%3A+Collect+and+Expose+Client%27s+Name+and+Version+in+the+Brokers]] made it possible to see what library versions are used by the Kafka clients.
> When Kafka brokers are connecting to other brokers this information is not properly populated, we see the "unknown" value instead for both `ClientSoftwareName` and `ClientSoftwareVersion`.
